Hello!
I am having some problems making my docking station work well with Zorin OS 16 Pro.
The Dock is Dell D6000 and my laptop is Acer 5750G
If I leave the docking station plugged in and then start the computer, I only see a dark screen, and nothing else. No keys combination work, even though I unplug the docking station
If I start the laptop and then plug in the docking station then it works somehow:
if I press Win + P, then the image goes live on one external monitor and everything else is dead. I need to force the shut down by pressing the power button
if I go to Display settings, I see one monitor, I slightly adjust the position of it and press Apply. Then I press Win + P, it detects all my monitors and the docking station works.
But the problem is when I shutdown, because it gets stuck at killing xorg server and it does not shutdown ever.
Now, I have tried with both Nvidia video card drivers and zorin's drivers
The docking has the latest firmware installed.
What can I do?
I mention that on Windows 11 the docking station works without problems and I thought since Zorin OS is based on Ubuntu 20.04 it should work without problems
Do you have any Kernel parameters added to your grub file?
If not, you may try
sudo nano /etc/default/grub
Find the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and change it to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1"
ctrl+x to exit, then the y key to say yes to save. Then the enter key to save as current configuration.
Reboot and test...
If no good, try: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash ide=nodma apm=off acpi=off vga=normal noapic nolapic"
I have tried you 2 suggestions, but if I leave the docking station plugged in, I get a black screen on all the displays(integrated one + external monitors).
Also, I am using the latest Nvidia drivers (390) for my video card.
I will try also with driver 340
Is that driver 390.144 ? That is the only driver that will work with the 5.11 kernel
Release Highlights:
Fixed a bug where vkCreateSwapchain could cause the X Server to crash when an invalid imageFormat was provided.
Fixed a driver installation failure on Linux kernel 5.11 release candidates, where the NVIDIA kernel module failed to build with error "fatal error: asm/kmap_types.h: No such file or directory".
i am not familiar with dual graphics, i have 1 card in my notebook. My wife has 2 but they work out of the box. I don't know if he can switch off the intel so the nvidia will take everything over.
Pop! OS, she said she did not care as long as it is not Microsoft Windows. She got mad after the MS updates killed here wifi card. Pop! OS discovered both cards (AMD Radeon HD 7670M and the Intel 4000), today she upgraded to kernel 5.15.5 and still working. Machine is 8 years old.
Such anecdote makes me wonder if it is more reasonable to advise people with a similar setup to go for POP, not Zorin.
I routinely advise people with 2GB RAM or less to go for MXLinux or Linux LIte.
The story continues like this:
After more searching on the internet I found the a patched xorg server and installed it (DisplayLink XServer Patch 20.04 | Synaptics) which led to a system break. I could not log on to Zorin.
After more searching, and booting in emergency/rescue mode , uninstalled old xorg, and resintalled it, then the system booted up normally, and the docking station works as expected.
Also in Additional drivers I see that now is using X.org.X server -- Nouveau display driver from xserver-xorg-vide-nouveau (instead of Nvidia driver which it used before)
As a conclusion, I do not know what exactly made it work, but now it works, it recognizes my monitors if the docking station si already plugged in when booting.
thank you also for your help and ideas
